The object of the game is to protect your fruit orchard from insect fruit thieves, scoring points by exterminating the attackers.
Your fruit orchard is growing oranges, grapes, strawberries and bananas. You must protect each variety of fruit from waves of insects. Four waves attack oranges, grapes and strawberries. Then, unlimited waves of insects attack your bananas. Each wave starts out with three fruit and four Master Nests.
You begin each game with four bug blasters in reserve. If you manage to save all three fruit from an insect wave, you're awarded an additional blaster. You can only have up to four reserve blasters on the screen at one time.
Each time you exterminate an attacking insect, you score points.
